What is the difference of enthalpy of formation and the enthalpy of combustion?
Enthalpy of combusion is energy change when reacting with oxygen. Enthalpy of formation is energy change when forming a compound. But some enthalpies can be equal.ex-Combusion of H2 and formation of H2O is equal
Equation for the heat of formation of carbon disulphide?
C + 2S -> CS2 Enthalpy of formation is the change in enthalpy for the formation of a substance from its elements.
What is Enthalpy of formation of chloroform?
There are several different measures of enthalpy. See link for some information.
What is the enthalpy of formation of sucrose?
I can not find this in any literature but using a theoretical calculation the enthalpy of formation of fructose is -1087.32 kJ/mol. This calculation was made using Spartan 08's T1 model. This method uses a combination of ab initio calculations and basis sets to create a correlated model. For a comparison, using the same calculation glucose's enthalpy of formation was calculated to be -1038.63 kJ/mol. Wikipedia reports the enthalpy of formation of glucose to be −1271 kJ/mol, though no citation is provided, so assuming this value is accurate there is an 18.3% error in the glucose calculation. I am curious as to where this value was obtained since there is no entry for the heat of formation of glucose on NIST nor that I can find in the CRC handbook.
How bond formation and bond breaking related to enthalpy?
Enthalpy is the measurement of total energy change of a reaction. The energy of bond formation and bond breaking can be used to calculate the bond enthalpy of the reaction. Bond enthalpy is the enthalphy change when 1 mol of bond is broken. Therefore the general equation to calculate the enthalpy change is energy of bond broken subtract by energy of bond formation.
What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.

Why does oxygen gas not have an enthalpy of formation but ozone does?
Ozone gas has enthalpy of formation. It is due to the high altitude.
What is the heat of formation of NaCl?
The standard enthalpy of formation for sodium chloride is -411,12 kJ/mol.

What best describe the enthalpy of formation of a substance?
The enthalpy of formation of a substance is the amount of energy that was put in or evolved from the making of that substance from the individual elements.
What is the heat of formation of SO2?
The standard heat/enthalpy of formation of SO2 is -296.8 KJ
The Literature value of enthalpy ionization of alanine?
the leterature value of ioniazation enthalpy of alanine
How is the enthalpy of reaction related to the enthalpies of formation for the products and reactants?
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
